Inverted Mouse Wheel on Windows

Using a small mouse with the Surface Pro makes it a lot easier to use the "Desktop". The incredibly tiny touchpad on the removable keyboard is an exercise in frustration. And, there are still some occasions (particularly on the desktop) where physically reaching out and touching the screen either isn't natural or the targets are just too small for my lack of dexterity.

With the mouse attached, however, I soon found myself scrolling the "wrong" way. At home and work I use a MacBook Pro and I've grown totally accustomed to the inverted scrolling that Apple sprang on us with OS X Lion.

Luckily for me, there's a way to get the same behavior out of Windows 8 (and earlier versions).

1. First, find the Device Instance Path for your mouse. Navigate to Control Panel Mouse. Click theHardware tab and highlight your mouse in the list.

Since the mouse I care about is removable, I turned it off and waited for one of the listed "mice" to display a status of "Device is not connected". Click [Properties], then select the Details tab.

From the Property drop-down choose "Device Instance Path" and note the value.

2. Now launch the Registry editor (regedit.exe) and Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\{Path from the Previous Step}\Device Parameters

Double-click the registry entry for FlipFlopWheel and change the Value data from 0 to 1.

Close the registry. You may have to disconnect and reconnect your mouse to get the change to take effect.
